For students bothered by a bunch of new math definitions, this is a great activity. Students will be given a real-life situation, and use objects instead of numbers and variables, before being introduced to the definitions of function, input, output, domain, and range. Students can explore this on their own, and then you can have a class discussion on pages 1-4. Then, the teacher will slowly guide students through the last 2 pages of the packet, as students are introduced to the definitions, and the different ways to represent a function. Will take a whole class period.
